I measured 2 and went back to bed and it was still snowing. After shoveling and everything I remeasured 2 but was hrs after it stopped. I prob had the same as you. I’m at an even 20 for the year
Walt a Met here a few years ago here kind of explained the same thing saying the fine snow must have formed right below the warm layer . I’m in butler and had that fine snow as well most of the day . They were needle shaped when I examined them on my glove.
Sidewalks were terrible this am and side roads . Temps peaked at midnight at 33 than slowly dropped to a low of 30.8 at 430. What’s odd was the most ice I saw on trees was looking towards riverdale (also butler heights area behind hs )and Bloomingdale . Hills to my west and north are higher in elevation (kinnelon and west Milford) had no signs of ice in trees . I have a decent view of both areas from my street
